Overview
The QATM QPOL 300 A1-ECO+ is an automated single-disc grinding and polishing system engineered for precision, repeatability, and long-term operational stability in metallurgical, materials science, and quality control laboratories. Designed and manufactured in Germany, it employs a robust mechanical architecture combining high-torque direct-drive platen rotation with independently controllable head rotation — enabling both co-rotating and counter-rotating motion modes essential for optimizing material removal rate, surface planarity, and subsurface damage minimization. The system operates on the principle of controlled mechanical abrasion using bonded or loose abrasive media (e.g., SiC papers, diamond suspensions, alumina slurries), where precise regulation of load, speed, direction, and dwell time ensures deterministic microstructural preparation across diverse sample matrices — including ferrous and non-ferrous metals, ceramics, composites, and geological specimens.
Key Features
- 4.3-inch capacitive touchscreen interface with intuitive QATM user software, supporting multilingual operation and real-time process monitoring
- Integrated spin-dry function: platen accelerates to 750 rpm for 3 seconds at process end to rapidly remove residual slurry and coolant from the disc surface
- Modular platen assembly system — “full-disc design” eliminates need for separate mounting base, ensuring concentricity, rigidity, and thermal stability during extended operation
- Independent bidirectional control of both platen and specimen holder (clockwise/counter-clockwise), facilitating optimized shear dynamics for specific material systems
- Adjustable loading mechanism supporting both center-load (20–350 N) and single-point load (5–80 N) configurations, compatible with standard Ø50 mm holders and multi-specimen fixtures (up to 6 samples)
- Durable aluminum housing with powder-coated finish and impact-resistant polymer inner bowl for corrosion resistance and easy cleaning
- Energy-efficient LED illumination integrated into the working chamber for enhanced visual inspection during setup and maintenance
- Compatibility with optional Qdoser ECO or Qdoser ONE precision liquid dosing units for automated, programmable delivery of lubricants, coolants, or polishing agents
Sample Compatibility & Compliance
The QPOL 300 A1-ECO+ accommodates a broad spectrum of rigid solid specimens requiring metallographic or petrographic preparation, including but not limited to steel alloys, aluminum castings, titanium components, tungsten carbide tools, sintered ceramics, and mineral thin sections. Its pressure and speed control range meets requirements defined in ASTM E3, ISO 13097, and EN 10365 for standardized grinding/polishing sequence development. The system supports GLP-compliant documentation workflows when paired with QATM’s method management software — each stored protocol (up to 200) is assigned to user-specific accounts with password protection and audit trail capability. All electrical and mechanical subsystems conform to CE, EMC, and RoHS directives; water inlet interface complies with DIN ISO 228-1 (R½”) and supports pressure-rated operation up to 6 bar.
Software & Data Management
The embedded QATM control software enables full parametric programming of multi-step preparation routines — including rotational speed, applied load, rotation direction, dwell time per step, and automatic fluid dosing triggers (when Qdoser is installed). Each method is timestamped and associated with operator login credentials, supporting traceability under ISO/IEC 17025 and FDA 21 CFR Part 11 requirements when deployed in regulated environments. Methods can be exported/imported via USB storage for inter-system consistency or backup. Real-time status indicators display motor load feedback, temperature warnings, and fluid level alerts — reducing operator dependency and minimizing procedural deviation.
Applications
- Routine metallographic specimen preparation for optical and electron microscopy (SEM/EBSD)
- Preparation of cross-sections for failure analysis and coating thickness evaluation
- Standardized polishing of hard-brittle materials such as silicon wafers, dental zirconia, and refractory oxides
- Geological thin-section production requiring flatness tolerance <1 µm over Ø30 mm area
- Quality assurance in foundries, aerospace component suppliers, and additive manufacturing post-processing facilities
- Research-scale development of novel polishing protocols for emerging battery electrode or fuel cell membrane materials
FAQ
What is the maximum number of preparation methods that can be stored on the QPOL 300 A1-ECO+?
Up to 200 user-defined methods can be saved locally on the device, each protected by individual account access.
Can the system operate without an external dosing unit?
Yes — manual dispensing is fully supported; however, integration with Qdoser ECO or Qdoser ONE enables repeatable, hands-free reagent delivery aligned with programmed steps.
Is the platen speed synchronized with the head speed?
No — both platen and head speeds are independently adjustable and programmable, allowing flexible kinematic configurations including differential rotation ratios.
Does the system support automatic cleaning cycles?
While no dedicated wash cycle is built-in, the spin-dry function (750 rpm × 3 s) significantly reduces residual media retention, and the lift-up platen design permits rapid access to the bowl for manual rinsing or vacuum aspiration.
What safety certifications does the QPOL 300 A1-ECO+ hold?
It carries CE marking per Machinery Directive 2006/42/EC, Low Voltage Directive 2014/35/EU, and Electromagnetic Compatibility Directive 2014/30/EU, with full technical documentation available upon request.
